Can Xia Bo's tone sandhi clips be bought in a physical store?

Xia Bo C 1 is enough, because it is economical and practical, and the workmanship and use effect are equally excellent. It is also a professional voice clip that we often use in playing and competitions. Since 1980, the Shubb timbre interlayer has become the industry benchmark, and it has become the object to be imitated by all other timbre interlayers. For millions of musicians on this planet, Shubb is the first choice, and sometimes even the only choice. A true guitarist will never accept a compromise product.
